我们可以在Android中使用API​​禁用Youtube视频播放中的缓冲吗？

公共类VideoDialog扩展了YouTubeFailureRecoveryActivity {

我们需要在Android应用程序内播放多个视频，没有任何延迟，但是youtube Player APi中的初始加载时间很长。有没有办法降低视频质量取决于设备???

Answer 1

等等我在API提供的文档中发现了一些内容。看看

/docs/reference/com/google/android/youtube/player/YouTubePlayer.PlaybackEventListener.html#onBuffering(boolean)

或仅YouTubePlayer.PlaybackEventListener.html#onBuffering(boolean)

似乎有你需要覆盖的回调。

似乎有PlayBackEventListener为您提供了您正在寻找的onBuffering。
